Continuity mistake: Coop (new resident) has to have a dressing put on his face while a burn victim is being treated. In a later scene, he's assisting treating another patient and the dressing is gone. But a few minutes later, the patient dies and Coop's dressing is back.
Factual error: The kid from the car accident has had an orthopedic device called a halo put onto his head in order to immobilize his head and injured spine. This item is screwed directly into the skull and is very secure. However, when the doctors are giving the boy CPR, the halo stays stationary but the child's head moves back and forth inside of it. The halo should have kept his head still, or his head would have moved only if the halo moved.
